MM4005 YF — Scale variable
Usage  IMM  PGM  MIP
Syntax xxYFnn
Parameters
Description xx
[int] — Variable number.
nn [int] — Scaling factor.
Range xx — 1 to 100 (integers) and 101 to 120 (floats).
nn — -32767 to 32767.
Units xx
— None.
nn — None.
Defaults xx Missing: Error O.
Out of range: Error O.
Floating point: Error A.
nn Missing: Error C.
Out of range: Error C
.
Description
This command scales the values of a variable. The value of variable xx is
multiplied by the constant nn and the result placed in variable xx. If the
value of nn is zero, the operation is not performed and error H is generat-
ed. If the result of the multiplication is outside the -32767 to 32767 range,
the operation is not performed and error H is generated. The decimal part
of the multiplication result is truncated.
Returns None.
Errors A — Unknown message code.
C — Parameter out of limits.
H — Calculation overflow.
O — Variable number out of range
.
Rel. Commands YA
— Add to variable.
YD — Divide variable.
YS — Initialize variable.
Example 1YR3 | Load analog port #3 value into variable #1.
3YY1 | Copy variable #1 in variable #3.
3YA-32 | Subtract 32 from variable #3.
3YF0.5555556 | Multiply variable #3 by 0.5555556; if variable #1 represents a tem-
perature measured in degrees Fahrenheit, variable #3 will be the
equivalent temperature in degrees Celsius.
